factors affecting enzyme action

What are the 3 main factors that affects enzyme action

Temperature,pH,surface area

What substance is absorbed by the lacteal in the villi

Fatty acids and glycerol (lipid digestion)

What is affected during oh and temp change in enzyme

The shape of the enzyme making it unable to fit into the substrate

What happens to the rate of reaction as the temperature increases up to 37 and why

The rate of reaction will increase as the temperature rises this is because as the temperature rises particles gain more kinetic energy the fore colliding into each other more increasing the amount of enzyme substrate complexes

What does it mean when an enzyme becomes “denatured” and is it permanent

It’s when an enzymes’s specific shape changes due to temperature change and its permanent/irreversable

What is the meaning of optimum temperature of optimum pH

It’s when the rate of the enzyme action is at its highest /fastest in a human body the temperature that this happens at is usually 37 degrees

How does an enzyme change shape as its optimum pH moves away from its optimum level

The active site will can be which would slow the reaction down as the substrate can no longer fit it

Why might an enzyme found in the stomach have a different pH than an enzyme found somewhere else

Because they need to be able to function in the stomach’s acidic(hydrochloric acid)environment

What is the optimum pH for an enzyme

Optimum pH =7 but for some enzyme in the stomach with acidic conditions pH=2 but fir some enzyme in the small intestine (duodenum)with alkaline conditions pH=9
